Brick

MOLER

Moler bricks are available in a range of grades and combinations of strength, density and thermal conductivity. They are pre-fired and designed for a maximum service temperature up to 1000˚C (1832˚F).

Esspee’s range of Moler bricks exhibit, high mechanical strength, excellent insulating properties and retain their strength at elevated temperatures. They are resistant to thermal shock, have low permeability to gasses and are able to withstand mild acid attacks.

There are two main grades of moler brick which are categorised as follows:

Solid bricks

Solid bricks combine high mechanical strength with good insulating qualities. They are suitable for use up to 1000˚C (1832˚F) and are commonly used as backup insulation against refractory linings.

Porous

Porous bricks are lightweight and have very low thermal conductivity, moderate mechanical strength, low heat storage and low thermal expansion. Porous grades are suitable for temperatures up to 950˚C (1742˚F) offering low thermal efficiency and cost savings.
